Comment on the following expression? c = (n) ? a : b; can be rewritten as
1.if (!n)c = b; else c = a
2.if (n <= 0)c = b; else c = a
3. if (n > 0)c = a; else c = b;
4.All of the mentioned
Comment on the output of this C code?
void main()
{
int k = 8;
int m = 7;
int z = k < m ? k = m : m++;
printf("%d", z);
}
1.Run time error
2.7
3.8
4.Depends on compiler
For initialization a = 2, c = 1 the value of a and c after this code will be c = (c) ? a = 0 : 2;
1.a = 0, c = 0;
2.a = 2, c = 2;
3.a = 2, c = 2
4. a = 1, c = 2;
The code snippet below produces
void main()
{
1 < 2 ? return 1 : return 2;
}
1.returns 1
2.returns 2
3.varies
4.Compile time error
The output of the code below is
void main()

int k = 8;
int m = 7;
k < m ? k = k + 1 : m = m + 1;
printf("%d", k);
}
